Benefits of technology

[0017]This makes it possible to prevent a trouble that the cut-out regions are out of the images and to appropriately cut out and enlarge the images.
[0045]According to the present invention, it is possible to prevent an adjustment effect of the stereoscopic effect obtained by the parallax adjustment from being impaired by performing a digital zoom.

Problems solved by technology

However, with the apparatus disclosed in Japanese Patent No. 3653790, a desired parallax amount may not be realized in some cases depending on the zoom magnification or the parallax amount of the subject.

first embodiment

[0061]An image reproducing apparatus 10 according to a first embodiment of the present invention is an apparatus which stereoscopically displays inputted right and left images having a parallax therebetween on a display unit 17. FIG. 5 is a diagram illustrating an overall configuration of the image reproducing apparatus 10. As illustrated in FIG. 5, the image reproducing apparatus 10 includes a right and left images selector control unit 11, a selector unit 12, a digital zoom unit 13, a zoom information input unit 14, a parallax adjustment amount input unit 15, a parallax control unit 16, and the display unit 17.

[0062]The right and left images selector control unit 11 controls which one of a left image and a right image is to be processed by the selector unit 12 and the parallax control unit 16. Data of the left image and data of the right image to be stereoscopically displayed on the display unit 17 are inputted to the selector unit 12, and any one of the left image and the right i...

second embodiment

[0094]FIG. 11 is a diagram illustrating an overall configuration of an image reproducing apparatus 20 according to a second embodiment of the present invention. It should be noted that components common to FIG. 5 are designated by identical reference numerals, and detailed description thereof is omitted. The image reproducing apparatus 20 is different from the image reproducing apparatus 10 of the first embodiment in that the image reproducing apparatus 20 includes a parallax adjustment amount computing unit 18 instead of the parallax adjustment amount input unit 15.

[0095]The parallax adjustment amount computing unit 18 computes an appropriate parallax adjustment amount on the basis of the parallax between the left image and the right image. The calculated parallax adjustment amount is inputted to the parallax control unit 16. The parallax control unit 16 has the same configuration as that in FIG. 6, and calculates the shift amounts and the display ranges of the right and left image...

Abstract

In the image reproducing apparatus according to an aspect of the present invention, the parallax adjustment amount is modified on the basis of the digital zoom information, the shift amount and the display range of each of the right and left images in the horizontal direction are computed on the basis of the modified parallax adjustment amount, and the right and left images are trimmed in the horizontal direction to be displayed. Accordingly, irrespective of a digital zoom magnification, it is possible to stereoscopically display an image while always maintaining an appropriate parallax.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an image reproducing apparatus and an image reproducing method, and more particularly, to an image reproducing apparatus and an image reproducing method that are capable of performing a digital zoom of a stereoscopic image while maintaining an appropriate stereoscopic effect.[0003]2. Description of the Related Art[0004]There has been known a display apparatus which causes right and left eyes of an observer to simultaneously view two images having a parallax therebetween, to thereby cause the observer to stereoscopically view an image. In such a display apparatus, in a case where right and left images are enlarged by a digital zoom, a parallax amount on a display plane of the right and left images is accordingly enlarged.[0005]For example, it is assumed as illustrated in portion (a) of FIG. 1 that a right image 101R and a left image 101L having a parallax da therebetween are stereoscopica...
